Precision gauges used to check the diameter and tolerance of holes in machined components using the Go / No-Go principle, ensuring quick and reliable verification of internal dimensions.
Plug Gauges are precision gauges used to check the diameter and tolerance of holes in machined components. They operate on the Go / No-Go principle, allowing quick and reliable verification of internal dimensions. Plug gauges are widely used in manufacturing, automotive, aerospace, and engineering industries to ensure product quality and dimensional accuracy.
At Size Gauge, we manufacture high-precision plug gauges using high-grade tool steel and advanced manufacturing processes to ensure durability, accuracy, and long service life. Every gauge is manufactured under our ISO 9001:2015 quality management system and laser marked with size and tolerance for easy identification.
We manufacture special gauges as per your drawings and specifications.
Contact Our TeamUsed to check plain hole sizes using the Go and No-Go principle to ensure the hole is within specified tolerance limits.
